Molecular dynamics simulation of nanoindentation on amorphous/amorphous nanolaminates

Abstract The nanoindentation deformation behaviors of Cu80Zr20 (A)/Cu20Zr80 (B) amorphous/amorphous nanolaminates were studied by using molecular dynamics (MD) simulation, aiming to investigate the effects of heterogeneous interface and layer thickness on the hardness. It was found that there is a strong length-scale-dependence for the mechanical properties of amorphous/amorphous nanolaminates. There is a critical range of layer thickness h (∼1 nm
